✦ Synopsis

Abstract

This work, by means of Raman spectroscopy, studies the vibrational modifications of a silica‐based sol‐gel bioactive glass (77S) in direct contact with a simple TRIS‐buffered solution. The novelty of this contribution with respect to similar previous works consists in the adoption of an in situ setup, designed to avoid all kinds of external contamination. The time‐dependent formation of the characteristic vibrational features of surface hydroxy‐carbonate apatite (HCA) is evidenced, and followed as a function of contact time.

The in situ Raman microspectroscopic properties of an Antarctic fungus are investigated to assess the nature and the spatial localization of the main chromophores and to study their spectral changes under enhanced UV-B irradiation. The Raman spectroscopic features of spores in situ are consistent wi
